Well then: Let the player type in a command with 3 IDs (/duel 0 4 9). Either specify in what order the IDs should be listed (e.g. /duel <teammate> <opponent1> <opponent2>), or show the creator a dialog with the three players listed as listitems and let him choose his teammate. After that, show a dialog to specify the weapons. If the creators is done with all this, send out a duel request to the other 3 players. If one player declines the request, cancel the duel.
